RustDesk是RustDesk团队开源的一款远程访问和远程控制软件,主要由 Rust 编写,可以远程维护计算机和其他设备。 RustDesk存在授权问题漏洞，该漏洞源于使用基于功能标志而非会话授权连接类型来控制传入消息，且文件传输会话未清除这些标志，可能导致仅持有有效文件传输授权的用户注入键盘和鼠标输入并访问未保护的屏幕截图和显示捕获处理程序。

Vulnerability Title
RustDesk - FileTransfer Session Authorization Scope Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
RustDesk gates incoming control messages on per-capability flags rather than on the session's authorized connection type, and a file-transfer session does not clear those flags. A peer holding only a valid FileTransfer authorization can inject keyboard and mouse input and reach the unguarded screenshot and display-capture handlers, acting outside its granted scope.
